Benefits of technology

[0011]According to the battery housing structure in the present invention, since the interposition member is provided between the battery body and the housing member, the battery body can be prevented from being displaced in the housing member even when a vibration, impact or the like is applied to the battery housing structure. As a result, the electric connection between the electrode layer of the battery body and the conductor in the housing member can be preferably assured, and reliability can be enhanced.
[0013]Herein, according to the battery housing structure in the present invention, since the housing member which is larger than the battery body is used, the battery body can be easily housed in the housing member. Furthermore, since air exists between an outer circumference of the battery body and an inner circumference of the housing member, the insulating property can be assured, so that a heat releasing property can be enhanced.
[0015]The interposition member may be fixed to the housing member. In this case, the battery body can be effectively prevented from being displaced in the housing member.
[0021]In the above case, the battery housing structure in the present invention may further include a conductive spacer arranged between the lid member and at least one of the positive electrode layer and the negative electrode layer. Alternatively, the battery housing structure in the present invention may further include a conductive spacer arranged between at least one of the positive electrode layer and the negative electrode layer, and the insulating base material. In this configuration, it is possible to prevent displacement and escaping of the conductive spacer caused by the displacement of the battery body in the housing member. As a result, it is possible to prevent an electric connection defect between the electrode layer of the battery body and the conductor in the housing member, so that reliability can be enhanced.
[0027]In the case where the positive electrode layer and the negative electrode layer are laminated in the extending direction of the insulating base material, when the insulating base material is placed on a surface of a substrate, the positive electrode layer and the negative electrode layer can be arranged in an extending direction of the surface of the substrate. As a result, each surface of the positive electrode layer and the negative electrode layer can be opposed to the surface of the substrate. Therefore, each of the positive electrode layer and the negative electrode layer can be connected to an electronic circuit wiring or the like provided on the substrate, so that the battery body can be easily mounted on the substrate.
[0028]According to the present invention, it is possible to provide the mount type battery housing structure capable of preferably assuring the electric connection between the electrode layer of the solid battery and the conductor in the housing member, and capable of housing the battery body of the solid battery with high reliability.

Problems solved by technology

However, according to the configuration of the battery disclosed in the patent document 1, when the battery laminate (battery body) is displaced in the sealing case due to a vibration or the like at the time of production or transportation, an electric connection between the laminate connection electrode part and the case connection electrode part cannot be preferably assured.

first embodiment

[0056]As shown in FIG. 1, according to a first embodiment of the present invention, a surface mount type battery housing structure 1 is composed of the cuboid-shaped battery body 10, and the housing member 20 for housing the battery body 10.

[0057]An all-solid-state secondary battery, serving as the battery body 10, for example, includes the solid electrolyte layer 13 sandwiched between the positive electrode layer 11 and the negative electrode layer 12. The positive electrode layer 11 contains, for example, Li2FeS2 or LiCoO2 as a positive electrode active material, and Li2S—P2S5 series composition or Li3PS4 as a solid electrolyte. The negative electrode layer 12 contains, for example, graphite as a negative electrode active material, and Li2S—P2S5 series composition or Li3PS4 as the solid electrolyte. The solid electrolyte layer 13 sandwiched between the positive electrode layer 11 and the negative electrode layer 12 is Li2S—P2S5 series composition or Li3PS4. Furthermore, for exampl...

second embodiment

[0078]As shown in FIG. 9, according to a surface mount type battery housing structure 2 in a second embodiment of the present invention, the insulating base material 21 has a recessed part for housing the battery body 10, and the metal lid member 22 has a plate shape. The interposition member 40 is provided between the battery body 10 and the insulating base material 21 serving as one part of the housing member 20. Another configuration of the battery housing structure 2 is the same as that of the battery housing structure 1 shown in FIG. 1. The battery housing structure 2 can also achieve the same advantageous effect as that of the battery housing structure 1.
